+
+2016-xx-xx - lavc 57.33.0 - avcodec.h
+ xxxxxxx - Add AVCodecParameters and its related API.
+ xxxxxxx - Add av_get_audio_frame_duration2().
+
+2016-03-11 - xxxxxxx - lavf/lavc 57.28.101
+ Add requirement to bitstream filtering API that returned packets with
+ size == 0 and side_data_elems == 0 are to be skipped by the caller.
+
+2016-XX-XX - xxxxxxx - lavf 57.28.100
+ Add protocol blacklisting API
+
+2016-02-28 - xxxxxxx - lavc 57.27.101
+ Validate AVFrame returned by get_buffer2 to have required
+ planes not NULL and unused planes set to NULL as crashes
+ and buffer overflow are possible with certain streams if
+ that is not the case.
+
+2016-xx-xx - xxxxxxx - lavc 57.27.100 - avcodec.h
+ "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing
+ the reset of the ASS ReadOrder field on flush. This affects the content of
+ AVSubtitles.rects[N]->ass when "sub_text_format" is set to "ass" (see
+ previous entry).
+
+2016-xx-xx - xxxxxxx - lavc 57.26.100 - avcodec.h
+ Add a "sub_text_format" subtitles decoding option allowing the values "ass"
+ (recommended) and "ass_with_timings" (not recommended, deprecated, default).
+ The default value for this option will change to "ass" at the next major
+ libavcodec version bump.
+
+ The current default is "ass_with_timings" for compatibility. This means that
+ all subtitles text decoders currently still output ASS with timings printed
+ as strings in the AVSubtitles.rects[N]->ass fields.
+
+ Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
+ timing is limited to a 1/100 time base, so this is relevant for any subtitles
+ format needing a bigger one), ease timing adjustments, and prevents the need
+ of removing the timing from the decoded string yourself. This form is also
+ known as "the Matroska form". The timing information (start time, duration)
+ can be found in the AVSubtitles fields.
+
+2016-xx-xx - lavc 57.25.0 - avcodec.h
+ Add AVCodecContext.hw_frames_ctx.
+
+2016-xx-xx - lavfi 6.36.0 - avfilter.h
+ xxxxxxx avfilter.h - Add AVFilterLink.hw_frames_ctx.
+ xxxxxxx buffersrc.h - Add AVBufferSrcParameters and functions for handling it.
